摘要:
An apparatus capable of continuously measuring and recording electret strength is described. It consists of a mechanically driven condenser whose induced voltage, due to the electric field of the electret, is filtered and amplified before being applied to a recorder. Some experimental observations of the transition from heterocharge to homocharge are presented.
